Historically speaking, one of the most important Pitchers in Latin America is Dennis Martinez, and he was also one of the most tenured.

The greatest Pitcher to come out of Nicaragua, Dennis Martinez had the best years of his long career with the Montreal Expos where he would be a three-time All-Star and won the ERA title in 1991.  Martinez would finish fifth in National League Cy Young voting that season.  Martinez had 100 of his 245 with the Expos, and had a 3.06 ERA with 973 Strikeouts.
